Comment:

 0001-rts-posix-Select.c-remove-unused-select_succeeded.patch is a cleanup
 patch removing unused variable
 0002-rts-posix-Select.c-search-for-EBADFs.patch is a patch, that finds bad
 file descriptors passed to select()

 What is the easiest way to convert such TSOs into IOException thunks?

 Thanks!
